I have a datagridview, 3 textboxes, 1 NumericUpDown and a button.What I want is that when the user clicks the button, the current row that is selected in the datagridview will change to the values in the textboxes and NumericUpDown.
View 4 RepliesHow would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.
Private Sub btnLaserGenerateTicket_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLaserGenerateTicket.Click

I have a datagridview hooked up to a bindingsource. I have a comboboxcolumn. Now, I only want the combobox to be visible if a new row is being added. Otherwise, that column should not be editable. How can I achieve this. If so, on what event should I add code.

I am having trouble with multiple selected rows in a DGV. I have the following line to test how many rows have been selected.
Dim NoOfRoomsSelected As Integer = MonthDGV.SelectedRows.Count.ToString But each time the value comes back as 0.MSDN says : The SelectionMode property must be set to FullRowSelect or RowHeaderSelect for the SelectedRows property to be populated with selected rows.I have this set to RowHeaderSelect.
I'm doing a simple search of rows in a DataGridView. If the search finds a record matching the search criteria that row gets selected. I just added the BindingSource.Find method
If the row I'm searching for is currently showing in the DGV's viewable area, then my code will find the record, if it's not showing, meaning you have to scroll up or down to see the record, my search does not find the record.
(Correction: It finds the record but the DGV does not scroll to have the selected row be in the viewable area.)
Here's my

Private Sub SearchForSite(ByVal site As String)
DeSelectAllDGVRows()

I have a datagridview in my application with numeric columns and date column. This datagridview is filtered by date. I want a label to show the sum of the filtered rows.
View 4 Repliesi need to group the rows of a datagridview rows basing on values in column1 of DGV.i mean for example while loop
if .Rows(TOPROW).Cells(0).Value =
.Rows(NextRow).Cells(0).Value then
color the rows with some unique color
else
color them differently
If I have an unbound DGV with hundreds or thousands of rows what is the easiest way to find any or all duplicate rows? ie. where the data in all the columns is the same in 2 or more rows.

I am having trouble adding a row to a databound datagridview on a parent form from a child form. I have two forms, one contains a datagridview that is bound to a table using 'datagridviewbindingsource' and contains an 'add' button. The second contains a checked listbox that is populated correctly and has a "Cancel" and an 'OK' button - when i check several items in the child form, i would like to hit okay and update the bindingsource of the datagridview on the first form with the checked items.
Code:
in form1 when btnAdd is clicked
dim f2 as new form2
'call it as a dialog to check for the cancel button
f2.ShowDialog()

I have a datagridview and I'd like to write it to a file in the same type of row and column format it's currently in.My first idea for doing this is to get the maximum number of characters in each column so i know how wide each column has to be formatted. Then loop through each row and write out each row while using the max characters in each column and the current cells content length to do the math to get the formatted columns to line up. Like the example below, except i'd have a lot more in it.
writer.WriteLine("{0,0}{1," & lb(2).Length + 50 - lb(1).Length & "}", lb(1), lb(2))
This takes label(1) and label(2) and writes them so no mater the length of either (to an extent) then will always be right hand aligned in two columns.

I'm trying to add functionality to my DGV that enables the user to edit the cell data and then save it to the datasource but I'm not getting very far. Right now, I'm just concerned with the editing the DGV part.
What's the best way to do this taking into consideration: A column of type date in hh:mm format will not edit. At the moment this column won't display the new edit and if I attempt to enter and display a string instead of a hh:mm rime format, I get an error)I need to provide validation for the value that is entered.There are loads of events for DGV cells
Can anyone tell me why "Rows cannot be programmatically added to the DataGridView's rows collection when the control is data-bound." I keep getting an error "Invalid Operation Exception was Unhandled" error. All I am attempting to do is allow the user to select products from a list(or a second datagridview) and have it added to the datagridview so they do not have to type in every cell since the other cells are not visible because they do not purtain to their needs. Plus they will be able to save all items at the same time.

It was even difficult coming up with a Question title for this.
Am not sure whether am using the right approach to my problem. See i have this datagridview that contains rows that i would like have saved back into the Database as new rows but with a column altered to a new value.
Eg
PKColumn1 FKColumn2
Column3 Column4
1 1
[Code].....
What am looking at is Change FKColumn2 (some foreign key, maybe i can also have a combo box somewhere on the form and an "import to") values to something like 2 and save the rows back to the database without loosing the original rows.
I want to only allow editing of one column in my DataGridView, but I want to allow the user to double click on any item in the row, and when the CellBeginEdit fires, force editing of my colum. I started by doing this:
Private Sub dgvCaptions_CellBeginEdit(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellCancelEventArgs) Handles dgvCaptions.CellBeginEdit
If e.ColumnIndex <> COL_CAPTION Then[code].....
But this throws an error in the BeginEdit(False) line because 'Operation is not valid because it results in a reentrant call to the BeginEdit function.' which of course it will do, but that is what I want. Is there another way to do this?
I have a problem with the database and the DataGridView. After editing the attributes of the database you can not see changes in the DataGridView. If you connect the DataGridView through code connection is correct. What could be the reason? What could be the fault of pliu nmd_piDataSet?
